Carbon fiber felt is a non-woven fabric, which is mainly made of carbon fiber through a dry forming process (such as air-laid), and then the finished product is obtained through hot rolling, needle punching, spunlace and other consolidation processes. Carbon fiber felt can be obtained by high-temperature heat treatment to obtain graphite felt. These two materials have excellent performance in thermal insulation, corrosion resistance and adsorption.
Microstructure of carbon fiber felt
Carbon fiber felt has a highly developed microporous structure, large adsorption capacity, fast desorption speed and good purification effect. Its microporous structure is composed of micropores of different sizes, with a micropore radius of less than 2 nanometers, a narrow pore size distribution and uniform distribution on the fiber surface. This structure makes the carbon fiber felt have a fast adsorption rate, fast adsorption speed and easy desorption for small molecules.
